Oh yes we experienced this. It was Chyle(I believe that's the spelling) It is basically the fluid from the lymph system. Erik had to go back in to the hospital and they put him on a NO FAT diet. (That stops the production of Chyle) He was on that for 5 days and when that didnt work, they had to go back in and do surgery to cauterize the spot where it was coming from.
Erik's wouldnt heal and kept leaking from his scarline and he also could get it into his mouth. I would think that the doctor would be concerned with the open wound that this is leaking from, as he should be healed from the surgery. I would ask the doctor about Chyle and push getting it cauterized, since I assume that your husband isnt eating a ton of things with lots of fat. It is a pretty easy fix once its diagnosed.
